showWSNTopicNamespace command

Use the showWSNTopicNamespace command to show the properties of a WS-Notification topic namespace. A topic namespace is a grouping of topics that allows information to be shared between applications.You use a permanent topic namespace to statically define the association between a WS-Notification topic namespace URI and a service integration bus topic space destination.

To run the command, use the AdminTask object of the wsadmin scripting client.

The wsadmin scripting client is run from Qshell. For more information, see Configure Qshell to run WebSphere scripts .

Command-line help is provided for service integration bus commands:

• For a list of the available WS-Notification commands, plus a brief description of each command, enter the following command at the wsadmin prompt:

  print AdminTask.help('WSNotificationCommands')

• For overview help on a given command, enter the following command at the wsadmin prompt:

  print AdminTask.help('command_name')

Purpose

This command shows the properties of a WS-Notification topic namespace in a human-readable form. There are two patterns for use of this command:
